Step-by-Step: How to Install Upgraded Brake Systems
Preparation: Ensuring Safety Before Beginning the Brake Kit or Big Brake Kit Install
- Lift and secure the vehicle: Start by parking on a level surface and engaging the parking brake. Use a hydraulic lift or jack stands to raise your car securely, ensuring stability throughout the process—your safety is paramount. Never work beneath a vehicle supported solely by a jack. Only begin when you have full lighting and the work area is free from clutter.
- Remove wheel lug nuts safely: Use a torque wrench or impact wrench to loosen (not remove) the lug nuts while the wheel is still touching the ground. Once lifted and supported, fully remove the lug nuts and set the wheels aside, noting the tightening sequence for later reinstallation. This prevents overtightening or cross-threading, which could compromise clamp force and create hazardous pedal travel conditions.

- Check brake fluid reservoir and protect surfaces: Before removing any brake components, verify the brake fluid level and prepare absorbent towels to cover painted surfaces. Brake fluid is corrosive and spills can damage both paint and metal finishes, so each step here protects your vehicle’s integrity as well as your skin and eyes.
Removing Old Brake Components
- Take off caliper bracket, brake pads, and front rotors: Begin with the outer caliper bolts—use proper-sized hand tools to prevent slipping. Slide off the caliper and suspend it with a wire to avoid excess brake hose strain. Remove the caliper bracket using a breaker bar if necessary, then slide off the old front rotors. Inspect all removed parts for uneven wear or damage, which could indicate underlying system gain or piston area issues in the brake system.
- Drain old brake fluid with caution: Open the brake fluid reservoir and, using a proper extraction tool, carefully remove old brake fluid. Dispose of used fluid per local regulations. Take care not to let the fluid level drop too low, as this introduces air into the system—a major cause of spongy brake pedal feel after reassembly.

- Inspect master cylinder and proportioning valve condition: Now is the time to examine the master cylinder for wear or leaks. Look for any brake fluid seepage, pitting, or damage in the master cylinder body or lines. Next, assess the proportioning valve: an incorrect or worn valve could create poor balance between your big front and rear brake systems, leading to uneven stop distances and reduced control.
Fitting the Big Brake Kit: Upgrading Front Rotors and Caliper Brackets
- Install new big front drilled rotors: Clean new drilled rotors with brake cleaner to remove factory coatings. Align the rotor on the hub, ensuring proper seating for maximum concentricity and reduced pedal vibration. This upgrade increases the thermal mass, aiding in reduced fade and consistent brake torque during repeated hard stops.
- Attach upgraded caliper bracket: Use new hardware where provided, tightening to specified torque in a crisscross sequence to maximize even clamp force. A securely mounted caliper bracket guarantees the upgraded system will harness input force efficiently and safely, minimizing unwanted pedal travel and maximizing cylinder and piston area effectiveness.

- Fit new brake pads: Clean all pad contact points on the caliper bracket and apply high-temp grease to limit noise. Properly installed brake pads—and compatible friction materials—are essential for translating pedal force and system gain into smooth, reliable stopping.
- Verify all hardware and lug nuts for proper torque: Double-check the tightness of lug nuts (but don’t final-torque until wheels are back on the ground) and caliper bracket bolts, as proper clamp force and sequence are critical to big brake kit safety and consistent brake system performance.
“Precision when installing every big brake kit part ensures consistent, fade-resistant stopping power.”
Integrating and Adjusting the Master Cylinder and Proportioning Valve
- Assess need to upgrade master cylinder for big brake performance: Big brake kits often require a larger bore master cylinder to match increased caliper piston area and maintain the correct pedal travel and firmness. Before proceeding, ensure compatibility—if in doubt, consult your kit’s documentation or your mechanic for recommendations. Incorrect master cylinder sizing can lead not only to mushy pedal response but also to reduced system gain and safety risks.
- Install or recalibrate proportioning valve: The proportioning valve is responsible for balancing brake force between the big front and rear brake assemblies. Installing an adjustable model allows fine-tuning for optimal control, especially if you’ve installed larger rotors and calipers up front. Secure correct alignment and tightness to avoid fluid leaks or mismatched brake bias.

- Double-check fitment for all new big brake and brake kit elements: Go through each installed part—front rotors, caliper bracket, brake pads, and new brake hoses—confirming every bolt and fitting is torqued to specifications and that fluid from the master flows uninterrupted through the system.
Finishing Up: Bleeding the Brakes and Final Safety Checks
- Use fresh brake fluid (compatibility with upgraded brake kit advised): With upgraded calipers and larger rotors often comes the need for higher-temp brake fluid. Always use fluid recommended with your big brake or brake kit. Fill reservoir to the correct fluid level before and during bleeding.
- Bleed all brake lines to remove air and ensure proper pedal feel: Bleeding is best accomplished with two people: one applying pedal force, the other opening bleeder valves at each wheel in the specified order (often right rear, left rear, right front, left front). This step ensures your big brake system achieves ideal clamp force, minimizing pedal travel and maximizing system gain.

- Inspect complete big brake kit assembly, all lug nuts, caliper brackets, and installed drilled rotors: Visually confirm each hardware piece. Spin the wheels by hand to check for pad and rotor clearance; listen for unusual friction or scraping (which could indicate misaligned caliper brackets or pad material issues).
- Test in a safe area for initial bedding of brake pads and rotors: Take your vehicle to an open space. Carefully perform a bedding procedure with repeated moderate stops to properly mate the new pad and rotor surfaces, optimizing brake torque and ensuring long-term performance.
